"This is the first interview I've ever done where I'm not wearing panties. Lucky you," says Kristen Bell. She has just stripped down for Allure's annual nudes shoot (in the May issue of Allure, on newsstands now). And so did three other courageous actresses: Minnie Driver, Jenna Dewan Tatum, and Nia Long. "I was a little bit nervous, but I actually really love my body—it's done amazing things for me," says Driver of the experience. "There's such a grace to being confident in who you are." We asked the women what it feels like to disrobe for America.
